A man today admitted killing his two children while they were visiting him for the weekend.
Jean Say, 62, pleaded guilty at the Old Bailey of murdering daughter Regina, eight, and son Rolls, 10.
They were found at Say's home in south London, on February 13 with stab wounds.
Say, a retired concierge who is originally from Ivory Coast, was remanded in custody to be sentenced on Monday.
He faces a mandatory life sentence but the judge Mr Justice Cooke has to fix a minimum term.
Say had separated from his wife Antoinette more than a year before, when she and the children moved out of the family home.
On February 12, Say received a letter confirming that he was facing eviction from the three-bedroom property.
Detectives believe he killed his children in the early hours of the following day to spite his wife.
Mrs Say, who is in her 40s, is believed to have alerted police after receiving a message from him.
She was in court today to hear him admit the killings through a French interpreter.
